Pulmonary Function Tests or PFTs are a set of tests that are used to determine, measure or observe the functioning of the lungs. The most common pulmonary function tests used are spirometry, gas diffusion, and lung plethysmography. 

Highlights of pulmonary function tests

A spirometry test is used to measure the amount of air inhaled and exhaled. It also measures the amount of time taken to complete a respiration cycle.
A lung plethysmography measures the amount of air in the lungs after the patient has taken a deep breath. It also measures the amount of air that remains in the lungs after the patient has exhaled as much air as possible.
What does a Pulmonary Function Test measure?
Pulmonary function tests would not only check how well the person is breathing but also how effectively the lungs are able to conduct oxygen to the rest of the body. In addition to air flow, these tests would measure the size and volume of the lung and lung diffusion.

These tests can also be used to measure

Total Lung Capacity   the amount of air present in the lungs after breathing in deeply
Forced Vital Capacity   the amount of air that can be exhaled after breathing in deeply
Minute Volume   the amount of air exhaled per minute
Vital Capacity   the total volume of air that can be breathed out after inhaling as much as possible
Tidal Volume   the amount of air inhaled or exhaled when breathing normally
Maximum voluntary ventilation   the amount of air that can be inhaled and exhaled in one minute
Functional Residual Capacity   the amount of air that remains in the lungs when breathing normally
Forced Expiratory Flow   the flow or volume of air during an exhalation
Peak Expiratory Flow Rate   the rate at which a person can exhale
When are Pulmonary Function Tests recommended?
A physician might recommend a patient undergo a PFT as part of a routine physical check-up. This test would be advised if the patient is experiencing any symptoms associated with lung problems or disorders such as asthma, respiratory infections, chronic obstructive pulmonary disease, COPD. A doctor would also use these tests to monitor and check whether a certain treatment prescribed for a lung disease or condition is working effectively.

Pulmonary function tests are safe as they are non-invasive but it is important to follow the instructions of the doctor or technician before, after and during the test. It is important to make your doctor aware of any surgeries, respiratory infections, chest pains or heart attacks that you might have experienced before the test. If you are taking any medications you might need to follow the advice of the doctor as to whether you can take them before the test.

Your doctor would also advice you on how to prepare for the test such as not eating a large meal, avoiding caffeine and wearing loose-fitting clothes. If you have any doubts, concerns or queries discuss them with your doctor.

Pulmonary Function Tests - Why Is It Required?

Diabetes is a chronic metabolic disorder that results in higher level of blood sugar in the body. It is assuming epidemic proportions and India has become the new diabetic capital with more than 50 million diabetic people. The main problem with diabetes is that it does not completely go away and there is a whole myriad of issues that it brings along with it. Heart attack, stroke, eyesight problems, delayed wound healing, nerve damage and impotence. Therefore, diabetes and by that we mainly mean blood sugar level has to be managed so that there is a delay in onset of the associated conditions and/or reduced in severity.

Ayurveda refers to diabetes as Prameha (excessive urination) and Madhumeha (sugary urine) and has identified close to 20 forms of the disease. According to Ayurvedic belief, each disease is caused due to imbalance in kapha, pitta, and vata doshas and diabetes is caused by all these, predominantly by kapha. With any stream of medicine, management of diabetes involves two tracks   one is lifestyle changes and the second is medications.

Lifestyle changes include the following:

    Diet: Reduce the amount of rice, sugar, potato, sweet fruits, maida, deep fried foods, and red meat. Protein-rich foods like lentils, soya, green leafy vegetables and fish should be increased. Diet plan should change to small, frequent meals instead of binge eating.

    Exercise: Include 30 minutes of regular exercise into your daily routine if you have a diabetic predisposition.

    Others: Avoid smoking and alcohol, ensure sufficient sleep, avoid sleeping during day time, improved foot and eye care, periodically check sugar levels and manage stress levels.

Medication

Ayurveda has a whole lot of home remedies which have proven to be very effective against diabetes:

    Jambhul: Eugenia Jambolana whether eaten raw or juice extract has been shown to have beneficial effects in managing sugar levels and cholesterol.

    Gymnema sylvestre: Used to manage diabetes for over 2000 years, it reduces sugar cravings and is being touted as the future for diabetes treatment.

    Bitter gourd (Momordica charantia): It has 3 components that give it strong antidiabetic properties. The charantin reduces blood sugar levels; the polypeptide has insulin-like effects; and lectin that again has hypoglycemic effects.

    Bel (Aegle marmelos): Also known as wood apple, leaves of the plant are shown to have antidiabetic properties. 5 to 10 leaves can be chewed on a daily basis to help control blood sugar levels.

    Fenugreek (Trigonella foenum graecum): Consuming 10 g of fenugreek seeds soaked in water increases the amount of insulin produced, thereby increasing sugar breakdown.

    Neem: Chewing about 4 to 5 leaves in the morning on an empty stomach helps to control blood sugar levels. Alternately, neem leaves powder is available which can be dissolved in water and consumed.

What is ADHD?

ADHD refers to attention-deficit hyperactivity disorder, which is a brain-related condition found among preschoolers, children, teenagers and in many cases extends well into adulthood. These individuals have significant impairment in academics as well as social situations and interpersonal relations. The child has difficulty sustaining attention, phases of hyper activeness and cannot control his/her impulses which make their day to day life at school and home difficult.

ADHD Symptoms

The symptoms of this disorder among children can be categorized under three headings.

1.Hyperactivity which includes

- Fidgets often
- Restlessness
- Inability to stay at one place runs around and tries to climb things
- Trouble playing quietly
- Excessive talking

2. Inattention, which can be divided into symptoms like

- Getting easily distracted
- Tendency to loose things
- Daydreaming
- Facing problems related to organizing things
- Not listening carefully
- Forgetting about daily activities, carelessness

3. Impulsiveness

- Interrupts others as they speak and talks out of turn
- Answers questions without listening to what has been asked
- Not being able to wait for their turn to come

Prevalence :

10-12% of school children before puberty are affected by one or more types of ADHD. ADHD especially hyperactivity is more prevalent in boys than in girls, with the ratio up to 9:1. Inattention and poor concentration are more commonly seen amongst girls. The rate of ADHD in parents and sibling of children with ADHD is 5-10 times higher than in the general population.

ADHD Causes

The probable causes of ADHD among children are,

1. Neurodevelopmental changes - Poorly developed activity of the brain particularly in the areas that control attention and concentration cause ADHD. This causes an imbalance in the neurotransmitters or the chemicals important for brain functioning and development.

2. Genetic Factors - genetic studies show that ADHD is largely hereditary in nature with a heritability of 75% approximately.



What are the Causes and Symptoms of ADHD?

Sometimes, during consumption of certain food items many children get itchy throat, eyes, ears, asthma, sneezing, rashes, diarrhea and eczema. This can be due to food intolerance in children. It is a form of allergic disease in children. Every 1 out of 10 children suffer from food intolerance. These days, food allergies are becoming more and more common in children who are allergic to nuts, milk and eggs. In some cases it can also be life threatening. This condition is known as anaphylaxis. Milk and egg allergies are more common throughout the world.

Symptoms of food intolerance:

Bloating

Your bowels start becoming irritable.

Stomach starts to ache.

Cough and cold is a common symptom.

Itchy skin rash

Causes of food intolerance in children:

There are enzymes in your body, which help you to digest the food you consume. Some enzymes in your body are insufficient; which further causes food intolerance in children. For instance, lactose intolerance causes spasms, stomach aches, diarrhea and so on so forth.

Food intolerance can also be caused due to chemicals, such as chemicals present in coffee, tea, cheese and chocolates.

Some food products can also cause food intolerance such as undercooked beans containing aflatoxins can cause extreme stomach infections in children.

Some children are also intolerant to certain food products which have salicylates such as majority of fruits, vegetables, herbs and also additives. Processed food contains a high amount of salicylates.

Children can be allergic to antioxidants like artificial food coloring, artificial flavouring and preservatives.

What to do if you think your child has food intolerance?

Take your child for a skin prick test. In this test, the skin is pricked with a thin needle and when the blood oozes out, supplements of different food products are put in that area. If that particular area becomes reddish and begins to itch, your child has allergy to that certain food product

A blood test should be done. It verifies the level of lgE present in your blood and finds out if your child is suffering from food intolerance or not. If you wish to discuss about any specific problem, you can consult a doctor.

Food Intolerance in Children - 5 Reasons Behind it

The term pollution means introduction of harmful and unwanted contaminants into our environment. Due to the borderless nature of our atmosphere and oceans, contamination at a small level can have a huge impact that to in places which are nearby and one of the best examples of this is crop stubble burning in Punjab and Haryana which is a major contributor to Delhi smog. Pollution is a slow poison and is deleterious to the life of all beings, including plants, animals, and humans. With the rise in the pollution levels, no one can escape the harmful effects of the same on health. Though pollution poses a great threat to everyone, it is the children who are most effected, let us read on to know the reasons

Why are children more susceptible to pollution?

The lung function, immune system, and metabolic systems in children are not fully developed and functional which makes it difficult for the body to fight these pollutants.
Children breathe in more air per kilogram of their body weight than adults, so they take in more pollutants per breath.
Children are not only more active but also have a faster breathing rate than that of adults. This means that they take in more environmental toxins and at a much faster rate.
What are effects of pollution on children s health?

Exposure of pregnant women to polluted air is strongly associated with premature birth, low birth weight, and intrauterine growth retardation. Low birth weight babies and premature infants are more prone to developmental delays and other disorders.
Exposure to certain pollutants like carbon monoxide and ozone are linked with septal and valvular defects in the heart of a child.
There is a strong association between particulate pollution and symptoms like wheezing and bronchitis in both adults and children. This is the main reason why there is an increased prevalence of Asthma in children in urban areas. Research has shown that high level of pollutants in air cause deficits in lung function growth.
The immune system which protects the body from infections and germs is not fully developed in children. Pollutants are known to cause suppression of immunity in small children making them more prone to infections.
Children need sufficient Vitamin D for strong and healthy bones. Vitamin D is known as sunshine vitamin and is synthesized in the body on exposure to UVB rays of the sun. Increased particulate components in the air reduce the amount of UVB radiation reaching the ground level. More than 60% children are Vitamin D deficient and require supplements orally.
The exhaust of gasoline and diesel is known to emit carcinogens which are thought to play a role in the development of leukemia (blood cancer) in children.
The nervous system is a target for many environmental pollutants. Exposure to these pollutants can lead to neurological deficits and delays in development. Some of these effects are irreversible and long-lasting.
Unfortunately, with urbanization and increased population, the levels of particulate pollutants in the air are increasing at an alarming rate. The problem of pollution needs to be addressed immediately, until then it is best to keep the children indoor and take necessary precautions and keep children safe from exposure to the pollutants.
